characteristic of has characteristic continuous with continuous with increased in magnitude relative to decreased in magnitude relative to insect sclerite conjunctiva Conjunctivae are more flexible and usually less thick than sclerties of the cuticle allowing the sclerites to move relative to each other. Micro-CT based methods cannot be used to accurately differentiate slcerites from conjunctiuvae. CLSM (the excitation wavelengths of sclerites and conjunctivae are different in response of 488 nm emission vawelength), histological sections or simple dissections need to be applied to define relative flexibility of the insect cuticle. If a conjunctiva entirelly encircles a sclerite, then the 'encircles' and 'encircled by' object properties are used to link the sclerite and the conjunctiva even in cases in which the encircled sclerites or conjunctivae are part of an evagination allowing to model spatial relationship between appendage segments: the pedicel is encircled by the scapal-pedicellar conjunctiva, which is encircled by the scape or the the coxa encircles the coxo-femoral conjunctiuva that encircels the femur.
